To all whom may concern.' Y

Be it known that I, ROY P. 'ROBERTS a citizen of the United State, residing at Chicago, in the county of Cook and, State of Illinois, have invented certain new and useful Improvements in Garbureter Attachments, of which the following is a'speciiication.

The object of my invention is the provision of simple and efficient means whereby the driver of a motor car employing an explosive engine may regulate from his, seat the flow of gasoleneor othercombustible liquid into the float chamber of the carbureter.

It is notable that the gasolene at the present time used for automobiles is'of inferior quality and in the absence of some heat does not readily yield to vaporization. This fact renders it extremely diticult to start the engine especially in cold weather. The result is that it is generally4 necessary to prime the motor. In certaintypes of carbureter, particularly in those employed in popular priced automobiles, inorder tol accomplish priming, one is required to raise the hood over the engine parts and manipulate a tickler by hand. `After this isv done the driver must return to his seat before he can employ the starting motor. In the attempt to insure success in starting the engine` and avoid the annoyance of again getting out from and into the car he is quite likely to over-exert the starting motor. This results in a premature running down` of the battery. It is desirable therefore from the standpoint of economy and convenience to prime the engine and employ the starting motor concurrently.

Aside from the aid in starting the engine, there are cert-ain other advantages in priming the motor, notably that the initial intake of clean, clear gasolene serves to loosen and remove any carbon which might be present. But because of the attending,inconvenience the added advantages will not be attained except incidentally.

I am aware that carbureters have been built embodying as an integral part thereof means accessible from the car for priming the motor, but my invention provides for the attachment of such means as a supplemental device tc `carbureters in which such provision is not incorporated by the maker.

Through the medium of my novel device Ait is possible to so modify existing carburet- -most suitably adapted for operation therewith, but obviously the construction shown maybe varied wit-hin the scope of the appended claims without departure from the spirit ofthe invention, wherefore the drawings and description are to be taken in an illustrative and not in an unnecessarily limiting sense. In the drawings:

Figure 1 is a view of a carbureter showing my device in operative connection therewith.

Fig. 2 is a vertical section through the float chamber.

Fig 3 is a detail of the cap member.

Fig. i is a detail ofthe finger.

Fig. 5 shows the connection arm.

In the drawing, the reference numeral 10 designates a carbureter having a float chamber 11 of common type wherein a float 12 through lever 13 and connecting rod 14C regulates the intake valve 15 to control the flow of gasolene into the gasolene chamber. The adjustment of the Heat, intake valve and connecting parts is of course dependent upon the Aposition of the duct or passage leading from the {ioat chamber to the mixing chamber. A It is usual and is apparent from Fig. 2 that the valve 15 is adapted to be kept open by the pressure of the incoming liquid until the chamber 11 is filled to a predetermined height, when the ioat 12, which is buoyed up by the liquid 16, acts through the lever 13, fulcrumed at 17 to depress the rod 14 and close the valve. As the gasolene is drawn ofi' to the mixing chamber the float subsides, the rod 14 is withdrawn and thevalve forced open.

The movements so far described are automatic and induced solely by the running of the engine. After the engine has been at rest and become cold it is desirable and frequently necessary to kenrich the combustible mixture by permitting an excess amount of liquid to enter the mixing chamber. This is popularly styled flooding the carbureter. ATo accomplish `this flooding;v it is necessary Ito allow more than the normal amount of gasolene to enter the liquid chamber 11. In order that this may be done the auto- `sary to raise the hood of the car.

matic regulating mechanism istem'porarily interfered with. The inlet valvel is allowed to remain open bypurposely withholding the rod 14. The iioat 12 is immersed in the liquid 16 by manually pressf ing down the pin or tickler 18 into engagementwith the'long arm'19 of the lever. VThe tickler is yieldably mounted in thecover 20 of the liquid chamber. Upon the release of pressure the pin will be returned to-.normal positio'nby the spring 21. I-Ieretofore in manipulating the tickler it has been vneces- Ijt' my invention be incorporated the driver'will be able to flood the carbureter from his seat. For this purpose I have provided an attachment comprising av cap or bracket vmember 22 Vhaving-a base 23 and side walls 24 which is'adapted tobe secured to the cover 20 by means of screws 25. It is a detail of good construction to employ where possible a common screw for attaching the member 22 v to the cover andthe cover-in turn to the top of the gasolene chamber. `Aperture 26 in the base 23 allows the member 22 to surround the tickler. The side walls 24 have alined openings 27. A finger 28 preferably three rsideclas at 29, 30 and 31 also has alined openings 32 in its side walls. An arm 33 has an angular portion which passes through the holes 27, 32, 32, 27 of the side walls 24, 31,.. 29, 24 vand is securely fastened to the finger' 28, by a rivet, screw, or other means 35 extending through the aperture 34 in the horizontal wall of the finger 28 and the hole 36in the arm 33. The nger 28 is so mounted in the member 22 that the side 30 lies directly above the pin 18. The arm 83 is suitably connected with a rod 37 leading to the foot or dash board 3S of the machine in` convenientY relation to the drivers seat. Pushing the button or pedal 39 at the eX.- tremity-of rod 37 will rock the vfinger 28 forward thereby depressing the pin 18 and the fioat 12 and withholding opposition to the. inward flow of gasolene through the valve 15.` My device is so simple and of such inconsequential weight that upon releasing the pressure on the button 39 the spring 21 will return allv parts to normal position. Manitestly the associated members between the finger and pedal will require yarrangement to suit the presence of neighboring parts.

I claim:

1. A device for priming an internal combustion motor comprising a tickler, an open ended bracket member having upstanding parallel side walls and a flat base provided -with a plurality of openings to allow for carbure'ter casing,

fastening said member to the top of the an actuating finger pivoted between said walls and bearing on the tickler, a connection between said finger and arterminal adapted to be positioned so as to be accessible from the operators seat through which movement is transmitted to the ticlzler of the carbureter.

2. A device of the character described comprising a` tickler, a cap member adapted to be attached tothe top of a carbureter and havinga liat base apertured to allow the ticller to project therethrough and to present alined openings whereby common lscrew.` may fasten both cap memberand carbureter top, said cap member also being'provided with upstanding walls, a tilting fin vger pivotally mounted between said walls,

and means adapted to be positioned so asi to be accessible from the operator-s position to actuate said tickler to permit a tree low of liquid into the liquid chamber of the carbureter, substantially as described.

3. A device of the character described comprising a ticller, a cap member adapted to be attached to the top of a carbureter and having a fiat base apertured to allow the tickler to project therethrough and to present alined openings whereby a common screw may fasten both cap member and carbureter top, said cap member also being provided with upstanding walls, a tilting finger pivotally mounted between said walls,

means to actuate said tickler to permit a walls and a fiat base provided with a plurality of openings to allow for fastening said member to the top ot acarbureter and to permit the tickler to project therethrough,

anactuating finger pivotally mounted between said side walls and adapted to engage with and vdepress said Yticliler, and means adapted to be positioned so as to be accessible from the operators position for transmitting movement to said finger.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
